DUMPING WAGON. -N0. 513,881. Patented Jan. 30, 1894..

UNITED STATES PATENT OFFICE.

BENJAMIN W. CLARK, OF WASHINGTON, DISTRICT OF COLUMBIA.

DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 513,881, dated January 30, 1894.

Application filed April 19, 1893- Serial No. 470,970. (No model.)

To aZZ whom it may concern Be it known that I, BENJAMIN W. CLARK, a citizen of the UnitedStates, residing in the city of Washington, District of Columbia, have invented certain new and useful Improvements in Dumping-Wagons; and I do hereby declare that the following, is a full,

clear, and exact description of the-invention,

thereby overcoming the objectionable features of prior forms of garbage-collecting devices.

In carrying out my invention, I provide a cylindrical receptacle so mounted as to be revolved to any desired extent with case, said receptacle being provided with one or more inlet openings closed by slides or gates. These gates fit tightly and are actuated by means extending outside the cylinder or receptacle. Within the receptacle are arranged plates which serve'not only as means for the support of the shaft or shafts which carry the pinions which actuate the slides, but they serve also as chutes or guides for the garbage as it is emptied from the receptacle. The receptacle is mounted upon yokes which are supported on the frame and these yokes are extended upwardly sufficiently to prevent lateral displacement of the receptacle. In order to prevent endwise displacement of the receptacle, I provide a band or rib on the receptacle and rollers on one of the yokes to cooperate therewith, the one being provided with grooves to receive a projection on the other. Preferably the grooves are in the rollers and the projection on the band.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.

My present invention is capable of embodiment in various forms, the one herein shown, however, being what I at present consider the preferable one. Parts may be used without the whole. I may sometimes employ in a complete device some of the elements hereinafter described in connection with other parts of a construction somewhat diiferent from that shown. It being understood, therefore, that while the form herein shown and described is the preferred form, the invention is not restricted thereto.

The invention is illustrated in the accompanying drawings which form a part of this specification, and in which 7 Figure 1 is a side elevation. Fig. 2 is a rear view. Fig. 3 is a substantially central vertical longitudinal section through the receptacle removed from the frame. Fig. 4 is a cross section, on a smaller scale, of the receptacle, on the line (E f-13 of Fig. 3. Fig. 5 is a like View of a slightly modified form or arrange-- mentof slide or valve. Fig. 6 is also a section on the line 2-2 of Fig. 3, and Fig. 7 is a detail showing one of the rollers and the band K in elevation.

Like letters of reference indicate like parts throughout the several views in which they appear.

Referring now to the drawings by letter, A is the front axle, A the wheels thereon, B the pole or thills, and B the seat, all of known or approvedconstruction.

O is the hind axle and O the wheels thereon. The hind ax'le is bent downwardly between the ends as shown best in Fig. 2, so as to bring the cylinder as lowdown as possible. A further object of thus depressing the axle is to provide space for the other parts as will soon be made apparent;

D D are the longitudinal portions of the frame or support. There is one on each side of the cylinder, each being provided atits forward end with an upwardly curved or goose-neck portion d as seen in Fig. 1, to provide space for the passage of the front wheels to permit of turning in a small space,-andthe forward ends are secured to thefront bolster or cross plate D in any suitable manner. The rear ends are supported upon the rear axle.

The extreme rear ends of theportions D are connected by a transverse piece E as seen in be described.

Fig. 2 which serves as a support for parts to They are further provided with outwardly-extending portions or flanges d as seen in Fig.1 to serve as steps to facilitate the introduction of the load to the receptacle.

F is the receptacle or body, preferably cylindrical in form, and arranged longitudinally of the wagon as shown. It may be constructed inany suitable manner. As seen in Fig. 3, it is shown as analogous to a cylindrical boiler having two heads or ends flanged as at f. At one end it is provided with a perforated plate F as seen in Fig. 5 which serves as a strainer to separate the liquid portion of the contents from the solid, whereby the water may be separately withdrawn and discharged to sewer when desired through the cook or faucet f provided for that purpose, as shown in Fig. 3.

The receptacle is provided with one or more openings for the introduction of the garbage. In this instance, two are shown. They are normally at the upper side of the receptacle, and each has a hopper G arranged about the same as shown. The openings are designed to be closed by slides or gates H which are arranged to move in suitable guides within the receptacle, and, as seen in Figs. 3 and 4 the gates or slides are provided upon their inner faces with racks g which are engaged and actuated by small pinions h on the longitudinal shafts H which are suitably journaled in bearings, as shown. These shafts are extended through the ends or heads of the cylinder and are provided with crank handles h by which they may be actuated. There are two shafts mounted independent of the other for independent actuation of the gates or slides. These shafts are preferably mounted as seen in Fig. 3, where they have bearings at their outer ends in the heads of the cylinder, and in the inclined plates I, arranged within the cylinder and also at their inner ends in similarinclined plates I. These inclined plates serve as chutes for directing the contents through the openings, and as housings or protections for the .pinions on the shafts H, as Well as guides and supports for the slides or gates, as will be readily understood from the drawings. Obviously, the inclined plates may extend entirely across the cylinder, thus dividing it into two main compartments.

Instead of operating the slides or valves in the manner just described, other means may be provided, for instance, as seen in Fig. 5, in which a shaft J is arranged at the axial center. of the cylinder and the valve or slide connected therewith by means of the radial arms j, the slide or valve moving in guides the same as before.

The cylinder is provided at each end and near the middle with an exterior band K, as seen in Fig. 1,the band at the rear end being provided with a rib or projection 0, which rib or projection is designed to work in the grooves of the rollers L which are mounted to revolve in the rear yoke M, as seen in Fig. 2. This prevents end displacement of the cylinder. The yokes are provided with lateral extensions m which are yieldingly supported upon springs N held in sockets n on the frame as seen in Fig. 2, the extensions working through vertical slots in said sockets and preferably provided with T-heads as seen in Fig. 2. The yokes are extended some little distance above the said extensions as shown in Figs. 1 and 2 to prevent lateral movement of the cylinder.

At its rear end the cylinder is provided with a large gear 0 which is engaged by the small gear P carried by a short shaft journaled in bearings in a bracket P suitably supported at the rear of the frame, as seen in Figs. 1 and 2, said shaft being provided with a crank handle 0 by means of which the same may be turned to revolve the cylinder when desired.

The operation will be readily understood from the foregoing description when taken 1n connection with the annexed drawings, and a further detailed description thereof is not deemed necessary. It is, however, briefly stated, as follows:-Normally the cylinder is in the position in which it is shown, with the hoppers uppermost and the slides or valves closed. When the attendant wishes to place anything in the cylinderhe has simply to turn one of the crank handles h and move the slide to uncover the opening in the cylinder and then introduce the garbage to the cylinder and turn the crank handle in the opposite direction to move the slide or gate into its former position. To bring the opening in the cylinder to one side and dump the contents, all that it is necessary for him to do is to turn the crank handle 0' until the cylinder is turned up side down.

Modifications in detail may be resorted to a without departing from the spirit of the invention or sacrificing any of its advantages.

All the bands K can be provided with ribs or projections to work in the grooves of the rollers, if desired, and such other changes may be made as fallwithin the scope of my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a dumping wagon, of a frame or support, a'plurality of yokes mounted on said support, anti-friction rollers mounted in the yokes, a cylindrical receptacle supported on said rollers, and means for rotating said cylinder to discharge the contents thereof, substantially as described.

2. The combination, in a dumping wagon, of a rotatably mounted receptacle having an opening for the introduction and discharge of matter, an annularly moving slide or gate provided with a curved rack and a shaft and pin ion for operating the slide to close and unclose the opening, substantially as described.

3. In a dumping wagon, a horizontally and longitudinally arranged cylindrical receptacle having an opening through one side shorter than the receptacle for the introduction and discharge of matter, and inclined plates leading from within to the edges of the opening to form a chute and thereby facilitate the discharge of the contents, substantially as de scribed.

4. In a dumping wagon, the combination of a cylindrical receptacle having side opening shorter than the receptacle and inclined plates leading from within to the edges of the opening, a frame or support upon which the cylinder is mounted and means for rotating the cylinder to dump the contents, substan tially as described.

5. In a' dumping wagon, the combination of a rotatably mounted cylindrical receptacle provided with bands, a frame or support upon which the cylinder is mounted, a plurality of yokes carrying anti-friction rollers, one of the bands or one set of the rollers being groovedto intergear with each other and thereby prevent longitudinal displacement of the cylinder with relation to its support.

6. In a dumping wagon having a rotatably mounted cylindrical receptacle having annular bands around the same, the combination.

of said receptacle and grooved supporting go rollers substantially as described.

7. In a dumping wagon, the combination of a support, a series of spring-supported yokes mounted on'said support, and a cylindrical receptacle having a series of bands around the same mounted in said yokes, substantially as described.

8. A longitudinally arranged rotatablymounted receptacle having opening and hoppers shorter than the receptacle with inclined plates within the receptacle forming chutes,

bearing for shafts and guides for the valves,

substantially as described.

9. A rotatably-mounted receptacle provided with openings combined with inclined plates within the receptacle, valves guided by said plates, shafts journaled in the plates and means on the shafts for actuating the valves and protected by the plates, substantially as described.

10. The combination with the receptacle, of a yoke provided with lateral extensions resting upon springs and with upward extensions for preventing lateral displacement of the receptacle, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.
